The working principle of the invention and process for using: the civil construction is with concrete strength experimental provision in use, first It is detected according to concrete self-strength, extracts the check lock lever 10 in the second locking hole 905 out, by mounting blocks 903 and squeezed Block 904 takes out out of mounting groove 902, then chooses concrete sample, test specimen is placed into 801 top of test specimen support plate, then Calibration operation is carried out, compression bar 7 is subsequently controlled by control cabinet 2 and is moved down, so that 901 bottom end of lower platen and concrete block top End fitting, senses the stress that concrete sample is subject to by sense base 4, is shown by the display screen on control cabinet 2, records number According to, and calculated in conjunction with correlation formula in the prior art；
When needing to test the flexural strength of concrete sample, first by the check lock lever 10 in the first locking hole 806 It takes out, then makes keel 804 swing to 801 top of test specimen support plate by two hole corner braces 803, then extraction auxiliary cushion block 805, and check lock lever 10 is inserted into the first locking hole 806 of keel 804, keel 804 is fixed, is then selected Suitable quantity and the mounting groove of position 902, mounting blocks 903 are placed into inside mounting groove 902, then check lock lever 10 is inserted into Mounting blocks 903 are fixed in two locking holes 905, concrete sample is then chosen, test specimen is placed into keel 804 and is pushed up End, then carries out calibration operation, subsequently controls compression bar 7 by control cabinet 2 and moves down, so that 904 bottom end of crushing block and mixed Solidifying soil block top fitting, senses the stress that concrete sample is subject to by sense base 4, passes through the display screen display on control cabinet 2 Show, records data, and calculated in conjunction with correlation formula in the prior art；
In above-mentioned experimentation, calibration operation is specific as follows: choose concrete sample, concrete sample center into Line flag rotates the second lantern ring 2405, so that 2406 end of locating rod is close to center then after concrete sample is put Position then rotates the first lantern ring 2401, so that calibration mobile jib 2402 is swung, and utilizes the card slot at 2402 middle part of calibration mobile jib 2403, which block 2406 end of locating rod, is fixed, and locating rod 2406 and calibration mobile jib 2402 are in 90 degree at this time, calibrates needle 2404 positions are aligned with 801 center of test specimen support plate, then finely tune concrete sample, so that the mark at concrete sample center Note is aligned with calibration needle 2404, and then guarantees that concrete surface stress does not occur eccentric situation, is reduced stress position offset and is led The test data deviation of cause；
When being recorded to data, can be used recording mechanism 22, by parcel shelf 2203 with installation axle 2202 be axle center put Level is moved and put, then shows oscillating rod 2205 out of accommodating groove 2204, then by the kelly of 2205 bottom end of oscillating rod 2206 snap onto L-type support bar 2207, are supported by kelly 2206 and oscillating rod 2205 to parcel shelf 2203, user Article can be placed on parcel shelf 2203 and record test data；
When needing cleaning work 1 table top of platform after test, turning knob 19 first, so that lifting screw rod 18 rotates, Lifting screw rod 18 is moved down by the screw thread engagement of lifting screw hole 17, because passing through rotation between workbench 1 and cabinet 11 Otic placode 15 and fixing axle 16 are rotatablely connected, so that lifting screw rod 18 slides in the support sliding slot 21 on 20 top of supporting block, and will The end of workbench 1 is propped up, so that concrete residue is on inclined 1 table top of workbench to cunning at 14 position of waste residue collection box Dynamic, most of concrete residue can be slided along 1 table top of workbench, and user only needs to carry out the concrete residue of corner It scans out, effectively increases the cleaning efficiency of concrete residue；
After cleaning out, pulling plate 2307 is pulled, so that dustcloth 2305 crosses control cabinet 2 and upper mounting seat 6, and is made Pulling plate 2307 is placed below 1 front end of workbench, is reduced dust by the erosion of front, rear and top to device, then will The soft magnetic stripe 2306 of 2305 edge of dustcloth is sealed 11 two sides of cabinet from fitting, and reduces dust from two sides to device Erosion pass through planar vortex by pulling pulling plate 2307 that dustcloth 2305 is placed on 2301 surface of storage box when next time uses Coil spring 2304 can effectively drive to be rotated around cloth beam 2303, and dustcloth 2305 is driven to be recovered to storage box by cloth outputting notch 2302 Inside 2301.
